• A body of mass 5 kg starts from the origin with an initial velocity $\overrightarrow {u\,} \, = \,30\hat i + 40\hat j\,m{s^{ - 1}}$. If a constant force $\overrightarrow {F\,} = - (\hat i + 5\hat j)N$ acts on the body, the time in which the y–component of the velocity becomes zero is

• Two balls of masses ${m_1}$ and ${m_2}$ are separated from each other by a powder charge placed between them. The whole system is at rest on the ground. Suddenly the powder charge explodes and masses are pushed apart. The mass ${m_1}$ travels a distance ${s_1}$ and stops. If the coefficients of friction between the balls and ground are same, the mass ${m_2}$ stops after travelling the distance
